My phone GT-S7582 does not start when powered on it only displays Samsung GALAXY S DUOS GT-S7582 and also it does not enter in to the download mode.
I had the same problem for the past two days, tried many things like pressing Recovery mode(vol up+power button+Home), wiping the cache clear, reseting into factory mode, etc.
- You should first install Kies3 on your PC and try again to go into the Download Mode (vol down+home+power button).
- Then connect your phone to PC using USB cable. Oh, before that, you should write down your Phone model (GT-S7582 and Serial Number which is an alphanumeric code, behind your phone after you remove your battery.)
- Then open Kies, go to
Firmware upgrade and initializationand do as prompted in next few windows.
- The download will start. Please make sure you don't disconnect the USB cable and You should have 3 GB of free space in your C: drive (in case your OS is Windows)
- Everything will be rest and your phone will be as good as new. Use Google account's backup to restore apps and settings...
